> FileSink affected by S3 eventual consistency
> --------------------------------------------
>
> Key: BEAM-5934
> URL: https://issues.apache.org/jira/browse/BEAM-5934
> Project: Beam
> Issue Type: Bug
> Components: io-java-hadoop-file-system
> Affects Versions: 2.7.0
> Reporter: Pawel Bartoszek
> Priority: P2
> Labels: stale-P2
>
> After upgrading to BEAM 2.7.0 and Flink 1.5.2 from BEAM 2.2.0) every day few
> times a day job throws _No such file or directory_ exception when trying to
> move temp bundle to the final location.
> After digging into the code it looks like it's kind of S3 eventual
> consistency problem. Where the HEAD request, used to check if the temporary
> file exists before copying it to final location, returns 404 and the whole
> copy operation fails.
> We use sharded writes(32). Job output arounds 256 files a minute. But the
> exception is thrown max 3 times a day - which suggest that there is some race
> condition somewhere.
>
> The case where S3 enforces eventual consistency is where the check if the
> file exist is being made before uploading the file. I checked the BEAM
> FileSink and couldn't find any logic that pre-check if the temp bundle file
> exists.

> Amazon S3 provides read-after-write consistency for PUTS of new objects in
> your S3 bucket in all regions with one caveat. The caveat is that if you make
> a HEAD or GET request to the key name (to find if the object exists) before
> creating the object, Amazon S3 provides eventual consistency for
> read-after-write.{code}
